Tommykaira ZZ Electric VehicleTeijin, a technology-driven global group offering advanced solutions in the areas of environmental value; safety, security, and disaster mitigation; and demographic change and increased health consciousness. announced that it will launch the world’s first polycarbonate-resin pillar-less automotive front window, installed in the Tommykaira ZZ electric vehicle (EV) produced by GLM Co., Ltd.

Launched by Kyoto University, GLM, an EV manufacturer is likely to acquire street-ready certification for the Tommykaira ZZ fitted with Teijin’s PC-resin window. On receipt of the street ready certificate, GLM will offer the window as a special equipment for the car from this autumn.

Use of PC resins in automotive front windows is not permitted due to safety standards. However, due to high resistance to abrasion and weather, Teijin’s PC-resin window will comply new Japanese standards that will become effective in July, paving the way for its use in the Tommykaira ZZ.

Automakers in the U.S. and the EU are increasingly looking for PC-resin products that meet new safety standards thus opening a market for Teijin’s PC-resin windows.Teijin has eliminated the need for the A-pillar in the window by increasing the thickness of the sheet. The transparent PC-resin window has clear sight lines for safer driving and more enjoyable sightseeing. The integrated PC-resin pillar-less window is 36% lighter in weight than an equivalent conventional front window with an A-pillar.

PC-resin solutions of Teijin are in use in plastic glazing, including for train and automotive applications, leveraging PC resin’s competitive advantages over glass, including 200 times greater resistance to impact and just half the weight. Teijin developed a new plasma enhanced chemical vapor deposition (plasma CVD) hard-coating technology in March.

PC resin meeting the Japan’s new safety standards will be available for automotive front windows.
